Specification of Letters Patent.

Patented Feb. 16, 1915.

Original application filed July 21, 1911, Serial No. 639,744. Divided and this application filed October 4,

To all rhom it may concern Be it known that I, Faun J. QUEST, a

a citizen of the United States, residing at Worcester, in the county of W'orcester and State of Massachusetts, have invented a new and useful DustCollector, of which the following is a' specification.

lihis application for patent is filed in pur suance of a requirement of t e Patent Office and is a division of my original application for patent filed July 21, 1911, Serial No. 639,744.

The invention relates particularly to the construction of a dust collector particularly adapted for use in carpet sweepers.

Referring to the accompanying two sheets of drawings forming part of this application for patent, Figure 1 is a side elevation of the improved structure; Fig. 2 is a sectional elevation thereof; Fig. 3 is a bottom plan view thereof; Fig. 4 is a partial front elevation of the front end piece which carries the suction nozzle; Fig. 5 is a side elevation thereof; Fig. 6 is a partial perspective view illustrating the connection of the dust collecting bag; and Fig. 7 is a partial plan view of a modified form of nozzle.

Referring to the drawings and in detail A designates a box having an open under side and front end. A yoked handle A is pivoted to this box as usual in carpet sweepers, so that the same can be moved forward and backward. The box is separated into upper and lower compartments by a diagonal partition B. Secured to the bottom of the upper end of this partition are blocks 1010, which carry bearings 11-11 in i which is journaled a shaft 12, secured on the ends of which are friction wheels D which are preferably coated with rubber. These wheels extend slightly below the bottomzof the box so as to support the rear of the same, and so that said wheels will be revolved as the cleaner is moved back and forth.

CC designate two air exhausting pneumatics, each having a fixed board 13 and a movable board 14, the movable board being hinged to the front end of the fixed board, and the two boards being connected by a yielding membrane or diaphragm 15. The lower board 14 of each pneumatic pro- Serial No. 652,800.

vided with a series ofholes 16, covering which is a suitable membrane valve 17 ar ranged on the lower side of the movable 22-22 on the two friction wheels D-D arepreferably set at 180 degrees to each other so as to provide a practically continuous operation.

of which is elevated above the partition B.

,E designates the dust collecting [bag which is disposed inthe upper compartment of the cleaner, and which has its body resting on thescreen S.

By elevating thescreen in the manner shown practically all the surface of the dust collecting bag is subjected to the induced vacuum. This is an important point in practice because the dirt accumulates on the bottom side of the dust bag and by allowing the induced vacuum to operate on practically all the surface of the dust bag, the surfaces of the bag which are not covered by dust are so arranged that they will performthe function of separation. By this arrangement, very little dust can go through the dust bag and the bag can be used until it is practically filled. The dust bagE is secured at its mouth or open end to a rectangular partition 23 which preferably is provided with leather faces 242 i 25 designates the front frame or end piece of the cleaner. Brackets 26 are secured to the sides of the' box near its front end and pivoted to the same are screws 27on which are threaded thumb-nuts 28. Secured to the front face of the end piece 25 are bear.- ing pieces 29 which have slots or holes 30 cut therein. Slots or holes 31 also are formed in the sides of therectangular frame Covering the holes formed in the partition B is a screen S, the top surface 23. The rectangular frame 23 and"front end. I.

piece are secured to the front of the box by turning the screws 29 to engage said slots 30 and 31, and by tightening up the thumb screw 28.1 13 loosening the thumb- .screws :28. and turning said screws 27 the front end iece 25 and the dust bag E can be remove frointhe cleaner.

The rear surface of I the front ehdQpiece 25 is provided with a moldin 32 which comes under the rectangular rame 23 so that when the parts are secured in position the said: molding will support the'rectangular frame 23. The front end piece 25 is pro-- vided with a rearwardly extending opening 250 which is arranged in position to communicate with the interior of the. rectangu'lar frame 23 andthus with the dust collecting bag E. This opening250 isextended down through the front endpiece 25 by a passage or communication 33 so that said'o enmg 250 will'connect with the nozzle. he

front end piece 25 is, rovided with a defleeting rib 34 arrange under the'opening 250, which deflecting] rib projects 'intothe dust collecting bag as shown in Fig. 2. This will form a tra under theopening 250 so that the dust or' irt collected n the bag will not shake outthrough the opening 250.

' through said The nozzle is formed on the-lower 'edge of the front end piece 25. This nozzle is preferably formed bya'bra'ss plate.35secured to the lower edge 1 of the front end 2, I

piece. This nozzle has a flat or. plane surface of a width indicated byfthe dimension '36 in Fig. 5; Cut in the brass plate are a series of'inlet orifices or openings H. 7 These orifices are cut so as to leave a number of straight diagonal ribs 350 between them.

The orifices preferably comprise a series of triangular openings alternately dis osed so as to be'separated by said straight iagonal ribs. Saidforifices are less in width than the plane surface 36 of the brass pla'teso asv to leave fiat bearing surfaces at the front and rear of said series of orifices, said bearing surfaces Zha'ving a width designated by the dimensions 37 37 in Fig, 5. Byfthis arrangement of straight diagonal ribs, the

- nap' of the carpet will be spread apartas the nozzle is' pushed over the same, and, the

closen en gagement of. theflsurfaces' 37 .437

therewith in front,'of and behind the bpenings will cause an ejflective'jrush of [air carpet. 4 H

It is desirable in some' 'ca'ses to vary the tension or air suction on the nozzles. To this end aninlet is provided intheconnection to the air nozzle, and means is provided for varying" the area oftheinletf This inlet preferably consists of "a series of holes 38 bored in the front of the front'en'd piece 25. A valve or shutter 39 is secured-on the end of a spring 40 Which is pivoted atflflto the front end shofvn, like parallelograms,

separate d nap clean the desired to clean, and the valve or shutter 39 is adjusted so that the desired air tension orsuction is obtained upon the carpet.

The device'is exceedingly compact, easy to manufacture, and efiicient in operation.

The details herein shown and described may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.
